Cognitive-behavioral therapy for obsessive-compulsive disorder: review of treatment techniques

Obsessive-compulsive disorder (OCD) is a chronic, impairing condition with an estimated lifetime prevalence in adults of 2.5%. Controlled treatment trials have demonstrated that cognitive-behavioral therapy (CBT) is an effective intervention for OCD. However, many individuals diagnosed with OCD do not receive appropriate, empirically validated interventions, perhaps due to limited knowledge of CBT among mental health practitioners. This article provides a review of CBT for OCD. Issues related to treatment delivery and assessment are presented and highlighted by an individual example.     

Association between overt and relational aggression and psychosocial adjustment in undergraduate college students

This study examined the relations between overt and relational aggression, social anxiety, loneliness, depressive symptoms, and alcohol and drug use in a sample of 287 undergraduate college students. Consistent with prior work, men reported engaging in more overt aggression than women. Contrary to our predictions, men also reported engaging in more relational aggression than women. Results also indicated that overt and relational aggression were positively associated with social anxiety, loneliness, depressive symptoms, alcohol use, and drug use for the overall sample. Hierarchical regression analyses showed positive relations between overt aggression and alcohol use for men and no relations between relational aggression and any psychosocial adjustment index. For women, overt aggression uniquely predicted social anxiety, loneliness, and depressive symptoms, whereas relational aggression uniquely predicted social anxiety, loneliness, depression, and alcohol and drug problems. Implications of these findings are discussed in terms of the role of peer aggression in students' psychosocial adjustment.     

A General Statistical Framework for Multistage Designs

Abstract. The efficiency of observational studies may be increased by applying multistage sampling designs. It is, however, not always transparent how to construct such a design to obtain increased efficiency. We here present a general statistical framework for describing and constructing multistage designs. We also provide tools for efficiency and cost‐efficiency comparisons, to facilitate the choice of sampling scheme. The comparisons are based on Fisher information matrices and the results are presented in graphs, where either efficiency or cost‐adjusted efficiency is plotted against a normalized measure of cost. The former curve resides in the unit square and is analogous to the receiver operating characteristic curve used for testing.     

Peer Victimization in Children with Learning Disabilities

This study examined the nature and psychosocial correlates of peer victimization in a clinical sample of children with Learning Disabilities (LD). A total of 303 patient charts were searched at a university child psychiatry clinic, and 77 participants met LD diagnostic criteria. Data collected included the Child Behavior Checklist (which contains items assessing peer victimization), Conners Parent Rating Scale, Revised Children’s Manifest Anxiety Scale, and Children’s Depression Inventory. Peer victimization was positively correlated with parent reports of withdrawal, anxiety, depressive symptoms, social problems, thought problems, attention problems, and disruptive behavior. Children with LDs who had comorbid psychiatric diagnoses reported a significantly higher amount of peer victimization than children without a comorbid psychiatric condition. Implications of this study regarding the role of peer victimization and healthy psychological adjustment among children with LDs are discussed.     

The planning of a department store

A town or village attracts people from its hinterland to purchase goods by virtue of the amount and variety of goods on offer. Similarly, a department store attracts customers away from cempetitors by means of displays, staff expertise, stock holdings and numerous other parameters. The store is generally free to manipulate these parameters subject to certain restrictions; the manipulation will have a direct affect on the ultimate profitability of the store. This paper describes some current research that is being carried out in conjunction with a department store group. The ultimate aim is to link the corporate planning of the group and each store to detailed socioeconomic data describing the population. Some aspects of the problem have been investigated in depth, some are currently being discussed and some have not been considered at all as yet. The latest position will be reported and hopefully some feedback will be engendered.     

WITHIN U.S. TRADE AND THE LONG SHADOW OF THE AMERICAN SECESSION

Using data from U.S. commodity flow survey, we show that the historical Union–Confederacy border lowers contemporaneous trade between U.S. states by about 13%. The finding is robust over econometric models, survey waves, or aggregation levels. Including contemporaneous controls, such as network or institutional variables, lowers the estimate only slightly. Historical variables, such as slavery, do not explain the effect. Adding U.S. states unaffected by the Civil War, we argue that the friction is not merely reflecting unmeasured North–South differences. Finally, the border effect is larger for differentiated than for homogeneous goods, stressing the potential role for cultural factors and trust. (JEL F15, N72, N92, Z10)
